A few months ago we hired someone that we knew quite well personally in a well paid, senior role and her behaviour has been really, really weird.
As background: she seems to have had a really great career, solid experience working for small companies doing quite niche work, very creative. But the move to our business is very different- different role, different type of business so she got the job mostly because of personal connections.
However! Since coming to work for us things got very weird, very quickly.
For reasons I can't understand, she started off throwing her weight around in a really aggressive way, sort of like demanding authority that doesn't belong to her. Then also treating other senior people with quite a lot of disrespect really needlessly which has resulted in complaints.
Now I've just found out that she told a junior staff member that she previously held an extremely senior role at a very well known brand, and I know this to be completely false. I find making up something like this to be quite worrying.
I've known this person for years and they were always well paid, seemingly successful and a normal CV. They've obviously got plenty of work experience so should know how to behave at work.
Beyond that she always seemed like a really nice, honest, moral type of person. Admittedly she was a bit of a shameless self promoter, but she was otherwise lovely so I overlooked it.
I'd stress she's been given a very well paid job in a nice company where nobody is competitive and she was welcomed very warmly so the behaviour is completely bizarre and we're struggling to work out what's going on.
I've tried speaking to her as have others and reactions have ranged between getting upset and claiming she's being picked on, patronising people, going on the attack or complete denial.
This has created a horrible environment at wirk, and her behaviour is just so odd that I'm hoping for help understanding it. She seems, behind the arrogance to be a bit fragile and so I'm not convinced formal discipline is the right route.
